Application filed December 26, 1914. Serial No. 879,052.

To all whom tr/Lay concern:

Be it known that I, FREDERICK H. lVnsToN,

shades or inclosures are used.

It is my aim to make the apparatus ordevices comprising these various parts simple andrugged in construction; easy and cheap to Vmanufacture gand secure, convenient, and reliable in use. K f

`My invention is especially advantageous in cases where one or more ot'the devices are to be supported by their current supply ineans,-as where strings of 'suspended lamps are employed for decoration purposes, for eXample,-and have accordingly described a particular construction einbodying it as especially adapted and applied to this purpose: but it will be understood that the utility .of the invention is not conlin'ed to this application, and that it can be otherwise carried out and embodied.

In the accompanying drawing, Figure 1 is a side view of a shade mounted and .sup-

ported in accordance with `my invention.

Fig. 2 isa view oi the mounting structure on a somewhat larger scale taken at an angle of 90 from Fig. 1, certain of the parts being separated from one another. Fig. 3 is a view of the mounting as seen from above, the uppermost or cover part being removed and omitted. Fig. 4 is a mid-sectional view of the lamp mounting structure without the shade. Fig. 5 is a view ot the mounting as seen from beneath, one of the parts being partly broken away. Fig 6 is a mid-sectional view of the mounting structure taken 90o from Fig. 4, the cover being removed and omitted. Fig. 7 shows the interior of the` shade neck as seen from beneath. Fig. 8 is a fragmental sectionalview illustrating the internal configuration of the shade neck in position to be*` 'applied to the mounting structure as shownabove it in Fig. 2.

Referri-ng,-ftiijst, fto'Figs. 1,12, and 3, it will be seen that the glass shade 1 is secured to a mounting structure 2 which is in turn secured to and supported by a cable 3 preferably comprising two individually insulated stranded conductors 4, 4, arranged side by side in a common braided covering The mounting structure 2 comprises a main cy-` lindrical body 6 (preferably of porcelain,v

bisque, or other insulating material) which has in its upper side a trough or trench-like groove or recess 7 that receives and accomniodates the cable 3 whose conductors 4,. 4, form part of the current supply circuit.l In the recess 7 are means for making electrical connection to the conductors 4, 4, shown as having the form of two conical ended screws 8,9 with their points slightly blunted. These screws 8, 9 are so arranged that whenv the cable 3 lis pressed sidewise into the recess 7 the ends of said crews will puncture the covering 5 and the insulation and be forced in among the strands of the conduc. tors 4, 4. Ordinarily the upper side of the, body 6 and the recess 7 are covered by a disl'f 10 of brass or other material which issecured to the body by screws 11, 11 engaged in internally threaded sleeves 12, 12 which are secured in holes in the body by their flanged, beaded, or expanded ends. (See Fig. 4). lVhen one of the mountings 2 is to -be secured and electrically connected to a cable 3, it is only necessary to place the latter over the recess 7 and the points of the screws S, 9 and to bring the cover 10 down.-

and foi-.ce it home with the screws 11, 1l

las shown in Figs. 1 and 4.

Referring, now, to Figs. 2, 4, 5 and 6, it will be seen that at the lower side of the cylindrical body 6 is a slightly tapering por tion 13'of reduced diameter on which are mounted and secured socket means for holding an incandescent electric lamp and making electrical connections thereto. As shown, the socket means comprise a screw shell contact 14 and a center contact consisting of the head of a screw 15. The upper end of the shell 14 is .expanded into a flange.

that `rests against the end of said reduced' portion 13 and isV secured thereto by means of the conical pointed screw S already referred to and an additional screw 16. '(See Figs. 2. 3 and The screw 8 is held fast b v a square nut 17 in a square recessv at the bottoni of the groove or recess 7, and the sci-ew 1 6 is held by a similar nut 18 similarly ioo 1'0 A 7 spectively, to the screws 8 and 9 so as to be cuit .conductors 4.

Itrwill be seen, therefore, that the shell and center contacts are electrically connected7 reproperly" connected by the latter to the cir- Still referring to Figs. will be seenthat in-the portion 13 of the body Gis a tansverse groove. and that in this groove. a metal strip 20 is secured be-v neath 'the head of the center contact screw 15. said sc'rew passing through the'nii'ddle of said strip.l cold-rolledsheet copper o'r othe/r springy, resilient-"fi "it rial. and the bot-toni of the upward bothways from thenriddle to allow free play to the endportions of the strip. The ends ofthe strp 20 are bent downward a little (see Fig. l) and t/heir corners are slightly turned down as shownfin Figs. -L and 5. The strip '20 is of such a length that both its ends project outward fr om the portion 13 lef the body 6, so as to perform their intended function as resiliently yielding secu ling members for'engaging the shade neck 21 internally and securing the shade 1 to the mounting structure '2.

IReferring, now. to Figs. 1, T. and 8, it will be -seen that the shade neck Q1 is of abcut the sameexternal diameter the body 6, so as vto merge ,with it in general outine and 'give the illuminating device, as a vhole, a good-appearance. At the upper end or edge of the neck, however, the glass is turned or offset inward to form an interal shoulder rI he opening within the boulder Q2 is, just a little larger than the portion 13 of the body. so that the latterv will fit within said shou der a little loosely.

At tnio diametrically pposite places the shoulder 2Q is interrupte and the glass wall of the neck Q1 carried stiaight up to its upper edge. the openings or notches Q3 thus formed in said shoulder permitting the securing members formed b v the ends of the metal strip 2O to pass. Diameti-ically oppo site and about 90o 'from the notches 23 are depressions Q-L in the lower surface. of the shoulder 22 in which sait. engaging members are engaged. These various features of the shade neck can best be produced b v forn'iing the upper portion of it of a reduced cross;

section'corresponding to the shape of the opening with the enlargements at Q3, 23. The upper end of the neck can be ground ofi' flat. and the inside can also be ground out to the exact size desired. This allows the nary. blowing methods.l

It willalso be seen that under a slight. force exerted to turn them with reference. to the'shculder 22, said securing members will yield transversely and leave said depressions 24, the sloping edges of the depressions (see'Fig. S) and Vthe beveled corners of-said securing members facilitating vthis.and that in this way the shade 1 can readily be removed from the mounting Q b v merely turning it about Vhen the bottom ofthe light-inclosure' or shade 1 is open'. any' desired style of incandescent electric lamp may obvicuslybe used with it: when it is closed. the opening of the neck 21 within the shoulder is sufficient to allow a tubular lamp bulb to pass.

Vliat I claim as new and desire to secure by Letters Patent of the United States, is 1 The combination with a shade yneck having an inwardly extending shoulder interrupted in a plurality of places and itself having a plurality of depressions. of a lamp mounting comprising a portion fitting within said shoulder of the shade neck, means forming a shoulder against which the end of the shade neck abuts. and a plurality of resilient members projecting from said portion and engaging beneath the shoulder Ain the neck in the aforesaid depressions therein, said members being adapted and arranged to yield transverselv and leave said depressions when said shade is turned with reference to the lamp mounting and to pass said shoulder where interrupted to permit removal of the shade from the lamp mounting. i

2. A lamp and shade mounting comprising an insulating body having in its upper side a recess for the conductors of a supply circuit and having at its lower side a reduced portion adapted to lit in the neck of a shade. means in said recess for making electrical connection-to the conductors eXtending therethrough. a lcover for said recess secured to said bodv. socket means for holding and making electrical connections\to an electric lamp seieured on said reduced portion of said bodv and electricallyconnect `125 ed to the aforesaid means in said recess. and means associated with said reduced portion of said bodv for engaging the shade neck to secure the shade to the body.

'3. A lamp and shade mounting compris- 15 ing an insulating body having at its lower side a transversely grooved reduced portion said reduced portion of said body, and a metalstrip secured in the groove in said reduced portion Withits ends projecting so asv to engage the shade neck internally and secure the shade on said reduced portion.

4, A lamp and shade mounting comprising an insulating body having at its lower side a transversely grooved reduced yportion Y adapted to fit in the neck of a shade, a screw shell mounted and secured on said Ireduced portion, a resilient metal strip in the groove in said reduced portion with its ends projecting so as to engage the shade neck internally and secure the shade on said reduced portion, and a screw extending' through said metal strip to secure it in said groove and serving as a center Contact for the lamp in said screw shell.

In witness whereof, l have hereunto set my hand this 24th day of December 1914.
